Sure thing, let's get straight to it. We start with 537 and we're going to multiply it by 18, which means adding 537 to itself 18 times.
Step 1: 0 + 537 = 537
Step 2: 537 + 537 = 1074
Step 3: 1074 + 537 = 1611
Step 4: 1611 + 537 = 2148
Step 5: 2148 + 537 = 2685
Step 6: 2685 + 537 = 3222
Step 7: 3222 + 537 = 3759
Step 8: 3759 + 537 = 4296
Step 9: 4296 + 537 = 4833
Step 10: 4833 + 537 = 5370
Step 11: 5370 + 537 = 5907
Step 12: 5907 + 537 = 6444
Step 13: 6444 + 537 = 6981
Step 14: 6981 + 537 = 7518
Step 15: 7518 + 537 = 8055
Step 16: 8055 + 537 = 8592
Step 17: 8592 + 537 = 9129
Step 18: 9129 + 537 = 9666

So, 537*18 = 9666
